Eliminate Risks – Reduce Running Costs
Measuring pH is a routine analysis in many laboratories, but many
things can go wrong in every day practice. The same applies
to conductivity, ion concentration, dissolved oxygen and redox
measurements. METTLER TOLEDO aims to assist customers in
reducing errors, getting accurate results quickly and enhancing their
overall lab performance. At the same time significant running cost
reduction can be achieved. With the Risk Check, a tool for analyzing
possible sources of error which in turn contribute to measurement
uncertainty, major risks can easily be determined and weighted.

Easy Five-Step Approach to Reach Best Practice
Good Electrochemistry Practice, GEP, is about guiding METTLER TOLEDO’s customers through
every step of the product lifecycle. The beginning is as important as the routine operation later on;
it is important to know who is measuring what, where and how often, to be able to select the most
appropriate products. This has to be followed by a correct installation and qualification of the equipment
as well as regular user qualification to guarantee good results.

The five steps are as follows:
1. Evaluation of the main aspects that may have an influence on the choice of an electrochemical
system.
2. Selection of optimal measuring equipment based on the evaluation above. The Sensor Product
Guide, which can be found on www.electrodes.net is a tool that has been developed to assist
when selecting sensors.
3. The installation of the system too poses risks and should either be done by carefully following
the installation checklist or professionally by a service technician.
4. Qualification—only properly qualified personnel and qualified equipment guarantee good results.
5. Routine operation provides the opportunity to apply all the work flows determined to be optimal
for the electrochemical system. This final step also requires the regular servicing of instruments
and verification of the methods as a form of continual fine tuning.
